LINECHEK®, Model 520L is a Line Leakage tester that is designed to run with Associated Research''s QUADCHEK® II, HypotUTLRA® II, HypotULTRA® III models to form a fully-automated test system that will perform both the eight most commonly specified Line Leakage tests as well as product safety tests in a single DUT connection. The system can then be controlled though our Autoware® control software or through the connected instrument. 520L will automatically perform these Line Leakage tests automatically without the operator having to manually configure the test.
